How to smooth footage in shake?

Okay, my footage I shot was pointing outside a cars window, and driving for 1 minute on the fwy.

I want to smooth this footage out to match my still footage I have of the driver against the green screen,

In the shot, the driver and car do not bounce around, but my broll I shot does!

So how can I smooth this out,

I tried the smooth cam node, and that created footage was is roated like crazy and not good.

Stabilize with 2 points would be the best, only that in my shot say reference point 1 and 2, (2 buildings in bg), get passed within 5 seconds, and I even pass through a tunnel so there arent any reference points.

How could one smooth this shot out?

Thanks.
